A man is running with a constant acceleration on a plank which is placed on a horizontal smooth surface. Then choose the correct option(s):

An open vessel containing liquid is moving with constant acceleration a on a levelled horizontal surface. For this situation mark out the correct statement(s).

A man of mass m is moving with a constant acceleration a w.r.t plank is .The plank less on a smooth horizontal floor If the mass of plank m then calculate the acceleration of plank and man w.r.t ground and frictional force extended by plank on man

A man is standing on a plank which is placed on smooth horizontal surface. There is sufficient friction between the feet of man and plank. Now man starts running over plank, correct statement is /are

A man of mass m is moving with a constant acceleration a w.r.t. plank. The plank lies on a smooth horizontal floor. If mass of plank is also m then the frictional force exerted by plank on man is ma/k. Find the value of k.

Two forces are applied on a system of blocks as shown. The block remains in equilibrium on the smooth surface. Then choose the correct option(s).

A man is standing on a plank which is placed on smooth horizontal surface. There is sufficient friction between feet of man and plank. Now man starts running over plank, correct statement is/are

A plank of mass M is placed on a rough horizontal surface. A man m walks on the plank with an acceleration 'a' while the plank is also acted upon by a horizontal force F whose magnitude and direction can be adjusted to keep the plank at rest. The coefficient of friction between plank and surface is mu . Choose the correct options. .

In the following problems, indicate the correct direction of friction force acting on the cylinder, which is pulled on a rough surface by a constant force F . A cylinder is placed on a rough plank which in turn is placed on a smooth surface. The plank is pulled with a constant force F . The friction force can be given by which of the following diagrams. .

A constant force F is applied on a spring block system as shown in figure. The mass of the block is m and spring constant is k. The block is placed over a smooth surface. Initially the spring was unstretched. Choose the correct alternative(s)
